SPECIFICATION forming part of Letters Patent No. 641,215, dated January9, 1900.

Application filed March 31, 1899.

To all whom it may concern.-

Be it known that I, FRANCIS MEISEL, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain Improvements in Machines for Cutting, Scoring, andEmbossing Paperfor Boxes, &c., of which the following is aspecification.

My invention has for its object to improve the construction and increasethe product of machines for cutting, scoring, and embossing paper forboxes and other purposes; and my invention consists in the several novelfeatures of construction and combinations of parts hereinafterdescribed, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of one side of myimproved machine. Fig. 2 is anelevation of the opposite side of thesame. Fig. 3 is a rear end elevation of the machine. Fig. 4 is anenlarged rear elevation showing the gripper-operating mechanism and themechanism for actuating the swinging table. Fig. 5 is a detail, partlyin section, showing a portion of the endless carrier-chain, one of itsgrippers, the gripperbar which actuates the grippers, itssupporting-bar, and thefront end of the swinging sheet-supporting table.Fig. 6 is a detail of one of the carrier-chain-locking devices. Fig. 7is a detail of the carrier-chain-operating mechanism. Fig. 8 is a planof the sheetsupporting table and the ends of the grippers.

Referringto the drawings, Arepresents the framework of the machine, insuitable bearings in which are j ourn aled two parallel shafts b c, oneach of which are fixed two sprocketwheels cl,which support endlesscarrier-chains B B, one on each side of the machine. The pins 6, Figs. 1and 4, which connect the links of said chains, engage the notches of thesprocket-wheels (1, whereby the chains are caused to travel a the samespeed and with :LpOSllilVO motion in the desired direction. The chains Bare provided on their outer sides with antifriction-rolls 25, placed atsuitable intervals, said rolls running on guide-rails 26 at the topofthe machine and in guide-grooves 27 in the framework, as shown in Figs.3 and 4.. These guide-rails and guide-grooves support, respectively, theupper and lower por- Serial No. 711,229. (No model.)

tions of the chains and prevent them from sagging in case they shouldbecome slack from wear or other cause. 7

C is the driving-shaft, which carries a driving-pulley D, to a crank-pinon which is pivoted a rack-bar E, which slides in a guide or casing fand meshes with a gear loosely mounted on a transverse shaft 72, towhich gear is secured a disk 28, carrying a pawl 29, adapted to engage anotch or tooth in a disk 21, Fig. 7, fast on the shaft h. A gear 30,also fast on the shaft h, meshes with an intermediate gear 31, thelatter meshing with a gear 32 on the sprocket-wheel shaft 0, anintermittent movement of the carrier-chain being thus produced as thedriving-pulley is rotated.

The sheets of paper 17 to be cut, scored, or-

embossed to form blanks for paper boxes or for other purposes are piledon a table G at the front of the machine and are fed forward singly byhand onto a table 33, pivoted at its outer end at 3i and provided with aside gage 1S and at its inner end with gages 35, which form stopsagainst which the front edge of the sheet is placed by the operator,ready to be seized by one of the several sets of grippers 1;, with whichthe bars extending between the chains B are provided, said chains ateach forward movement traveling a distance equal to that between twoadjacent sets of grippers. The gages 35 extend inward beyond thegrippers, so that the leading edge of the sheet when pushed forwardagainst said gages may be in a proper position to be seized by saidgrippers while the chains are at rest. The tilting table 33 is raisedfrom its lowest position, as shown'in Fig. 2, to its highest position,as shown in Fig. 5, before the sheet is fed onto it by the operator toinsure the leading edge of the sheet being pushed between the jaws ofthe grippers 2', and just before the chains commence to move said tableis lowered into the position shown in Fig. 2 to move the gages out oftheway of the sheet and allow it to pass without obstruction to thecutting, scoring, or embossing mechanism, to be hereinafter described.The table 33 is swung upward on its pivot and lowered at the propertimes by means of a toggle k, to one arm of which is pivoted a rod 38,the opposite end of which is pivoted to a lever 39, carrying a roll 40,which is acted upon by a cam 41 on the main shaft C.

At each forward movement of the chains B a sheet 17 is carried onto avertically-reciprocating member H, which cooperates with a stationarymember I, placed thereover, said member H being provided,as may berequired, with cutting-knives, scoring-rules, or embossing-dies properlydisposed to cut from the sheet, score, or emboss box-blanks or otherarticles. If preferred, the cutting-knives, scoring-rules,andembossing-dies may be secured to the stationary member I instead ofto the member 1-1. These members 11 I may be generically termedimpression members.

Immediately under the reciprocating member H on each side are placed apair of toggles J, connected by a horizontal bar 42. To one of thetoggles J is pivoted a slotted connecting-piece K, which slides on theshaft O. Within this connecting-piece K is placed the main cam 44, Fig.3, which is secured to the shaft 0 and acts on the cam-roll 45 tostraighten out the toggles, and thereby raise the member H. Outside theconnecting-piece K are secured on the shaft 0 cams 46, which act onrolls 47, mounted on a shaft at the lower endof the connecting-piece K,and serve to open .the toggles and return the parts to their normalpositions. The cams are so formed and timed as to permit the member H toremain at rest while the sheet is being drawn thereover and held by thegrippers 11. The grippers do not release their hold upon the sheetduring the time that it is being cut, scored, or embossed, and as soonas the member H has come to rest after its descent the carrier-' chainsare again set in motion, thereby causing the sheet which has been cut,scored, or embossed to be carried over a table L, when it is released bythe grippers and drops onto the pile on said table L, as shown in Fig.2.

I will now describe the construction of the grippers and the manner inwhich each set is operated to seize the front end of the sheet andafterward release the same to permit it to drop onto the table L afterbeing carried thereover by the movement of the carrierchains B,reference being had particularly to Figs. 1, 4, and 5. Between twoopposite links H n of the chains B B is secured a transverse bar 19, towhich are secured a series of grippers 2', (shown enlarged in Fig. 5,)each of which is composed of a stationary jaw 48 and a movable jaw 49,normally kept apart, preferably by a spring 50 placed between them, thevertical portion of the stationary jaw and the plate to which themovable jaw 49 is pivoted at 51 being secured to the bar 19 by screws52. The grippers are operated by a longitudinally-sliding bar q, Figs.3, 4, and 5, which bears against the movable jaws 49, as shown in Fig.5, said bar q being provided with inclined slots 53, through which passscrews 54,

by which it is fastened to the bar 19 in such manner that when it ismoved in the direction of the arrow, Fig. 4, it will, by the action ofthe inclined slots on the stationary screws 54, be moved on the bar 19,thus closing the jaws 49 against the action of the springs 50 andcausing the grippers to seize the sheet previously pushed against thegages by the operator. On the return movement of the bar q the inclinedslots cause it to be drawn back to the position shown in Figs. 3, 4, and5, which permits the springs 50 to open the grippers and release thesheet.

The bar q is slid first in the direction to close the grippers and thenin the opposite direction to open the same in the following manner: Onthe shaft 0 is a cam 60, Figs. 1 and 4, which acts 011 a roll 61 on alever 62, to which is pivoted a rod 63, the opposite end of which ispivoted to a bell-crank 64, secured to a short shaft 65. The upper armof the bell-crank 64 bears against a projection 69 on the sliding bar g,which is thus moved at the proper time to cause it to close the grippersupon the sheet. To the shaft 65 is secured a toothed segment 66, meshingwith another toothed segment 67 on a shaft 68, extending to the rear ordelivery end of the machine. On the shaft 68, at the rear end of themachine, is an arm 70, which bears against the side of the projection 69opposite to that in contact with the bell-crank 64 and moves the bar qin a direction contrary to the arrow, thus opening the grippers andreleasing the sheet, which then drops onto the table L be neath, thegrippers remaining open until they are again brought around to the frontof the machine ready to take a fresh sheet. In the machine hererepresented the carrier-chains are provided with six sets of grippersarranged at equal distances apart, but any suitable number of sets maybe employed to meet the requirements of the case. When thecarrier-chains B stop, the gripper-operating bars q of the frontgrippers to be closed on the sheet and the rear ones to be opened arealways in such positions that their projections 69 can be acted upon bythe arm of the bellcrank 64 and the arm 70 of the shaft 68.

As soon as the carrier-chains come to a stop they are locked to insurethe several sets of grippers being in their proper positions withrespect to the gages, the cutting, scoring, and embossing mechanism, andthe delivery-table by means of a bar r, sliding in a Vertical guide onthe framework and having its upper end shaped to engage amotch 73, Fig.7, in the hub of the gear 30, whiE-E is thus held stationary when thebar '1" is within the said notgh. The lower end of this bar r isconnected My means of a link 74 with a bell-crank lever 1 5, fast on atransverse rock-shaft s and having pivoted to its short arm a rod 76,also pivoted to a lever 77, fulcrumed at 79 and carrying a roll '78,which is acted on by a cam 80 on the shaft 0, said cam being timed toraise thelock- IIO ing-bar r and cause its upper end to engage the notchat the instant that the movement of the chains 13 is arrested.

On account of the lost motion between the chainlinks, sprocket-wheels,and gears I employ an auxiliary locking device which causes the chainsto be held positively at a predetermined point for the purpose ofbringing every sheet into precisely the same position at the terminationof each movement of said chains, thereby insuring perfect register. Thislocking device consists of two bars S S, one for each chain and eachprovided at its upper end with a semicircular notch, Fig. 6, forengagement with the pins 6, which connect the V links of thecarrier-chains, said bars S sliding in vertical guides on the frameworkA and being connected by means of bars 82 with arms 83, fast on therock-shaft s, which latter is actuated by the cam 80, as beforedescribed.

In order to diminish the speed of the carrier-chains j ust before thetermination of their movement, and thus prevent them from being carriedby their own momentum and that of their actuating mechanism beyond thedesired point, which would interfere with the proper operation of thelocking devices, I employ a brake consisting of a friction-strap w,encircling the hub of the gear 32 and connected at its upper end bymeans of a link 8% to a bellcrank 85, the latter being connected by arod 86 to a lever 87, fulcrumed at 88 and carrying a roll 89, acted uponby a cam 90, Figs. 3 and 4:, on the shaft 0, which is properly timed toapply the brake just before the termination of each intermittentmovement of the chains.

It is obvious that the above-described machine can be easily adapted forprinting by simply substituting a printing-form for the cutting,scoring, or embossing dies and employing the proper inking mechanism inconnection therewith.
